Wivenhoe release to close crossing
PLANS to release 25 per cent of the Wivenhoe Dam's drinking level will start later this week, closing Colleges Crossing for at least nine days.
A small controlled release is already under way at the dam through a partially opened gate, which is part of routine water supply requirements its operators said.
While arrangements are yet to be finalised, it is expected the upcoming major release will run for nine days in order to take best advantage of the current mild weather, tides and the limited flows into the Brisbane River from other sources downstream.
Colleges Crossing will likely be closed to all traffic during this time but the SEQ Water Grid manager in a statement said Mt Crosby Weir is open as an alternative route.
They also said if they were to continue with a 25 per cent release and keep Colleges Crossing open, the release pattern would need to be effectively doubled.
Twin Bridges and Savages Crossing will be impacted for at least 18 days and longer if there is rainfall in the Brisbane area or at the dam site.
The Captain Logan and Lumley Hill camp grounds at Lake Wivenhoe re-opened from last Saturday.
O'Shea's Crossing, the Spillway Lookout and Billies Bay / Hays Landing recreation areas remain closed until further notice.
